After being pulled from the App Store twice for objectionable content, the anonymous After School app is back with improved safety features, The Daily Dot reports. The app requires students to sign in with Facebook credentials to verify their location and school, then lets them post content anonymously to be viewed by others at their school. Bullies used that anonymity to torment other students, so After School’s parent company, One, spent three months improving the app’s safety. One co-founder Cory Levy said moderators now review every post before it goes live, with a “mature content” filter preventing anyone under 17 from accessing more adult posts. To verify age, the app will require a driver’s license scan. Students posting about harming or killing themselves will be referred to a 24/7 anonymous support team. Threats posted to the app will be flagged by an automated program that emails police and school officials. Even with the new safeguards, the App Store has After School rated 17+ for mature themes, mild sexual content, mild profanity and infrequent references to drug and alcohol use, among other things.
